It is occasionally necessary for Home Manager to change
configuration defaults in a way that is incompatible with
stateful data. This could, for example, include switching the
default data format or location of a file.
</para><para>
The <emphasis>state version</emphasis> indicates which default
settings are in effect and will therefore help avoid breaking
program configurations. Switching to a higher state version
typically requires performing some manual steps, such as data
conversion or moving files.
